  • FIG. 1 is a schematic perspective view of a motor vehicle door according to the present invention
  • FIG. 2 is an enlarged cross-sectional view taken along line II--II of FIG. 1;
  • FIG. 3 is a fragmentary elevational view showing a window frame and a vertical beam in the motor vehicle door;
  • FIG. 4 is an elevational view of the motor vehicle door as it is closed over a door opening in a motor vehicle body
  • FIG. 5 is an enlarged cross-sectional view taken along line V--V of FIG. 4.
  • FIG. 1 shows front and rear doors on the motor vehicle body of a motor vehicle such as an automobile. Both the front and rear doors shown in FIG. 1 incorporate the principles of the present invention. Since, however, the front and rear doors are of basically the same structure as each other, only the front door will be described below as a motor vehicle door according to the present invention.
  • the motor vehicle door has a reinforcing structure composed of reinforcing beams housed therein.
  • the motor vehicle door 1 comprises an outer panel 2 curved convexly outwardly as indicated by the imaginary lines, and an inner panel 3 extending relatively flatwise, the outer and inner panels 2, 3 being joined to each other into a hollow door body 5 in the form of a vertically elongate box.
  • the motor vehicle door 1 also includes a window frame 4 known as a window sash mounted on the upper end of the hollow door body 5.
  • the hollow door body 5 houses a window regulator for vertically moving a window glass panel into and out of the window frame 4. When the window glass panel is fully elevated into the window frame 4, the window glass panel has its edges sealed against the window frame 4, closing the window opening defined by the window frame 4.
  • the motor vehicle door 1 has a pair of upper and lower hinges 6, 7 positioned on a front end of the hollow door body 5 and vertically spaced from each other, and a lock 8 positioned on a rear end of the hollow door body 5 for locking the motor vehicle door 1 closed over a door opening 15 (see FIG. 2) defined in the motor vehicle body.
  • the upper and lower hinges 6, 7 are mounted on a vertical beam 10 that is disposed in the front end of the hollow door body 5.
  • the lock 8 is surrounded by a bracket 11 fixedly housed in the hollow door body 5.
  • the lock 8 and the bracket 11 may be of an integral structure.
  • a lower cross beam 12 obliquely extends from the bracket 11 toward the lower hinge 7, and has front and rear ends coupled respectively to the bracket 11 and the vertical beam 10.
  • the lower hinge 7 is fixed to a front vertical surface of the vertical beam 10, and the front end of the lower cross beam 12 is fixed to a rear vertical surface of the vertical beam 10. Therefore, forces can well be transmitted from the lower cross beam 12 to the lower hinge 7 or vice versa through the vertical beam 10.
  • An upper cross beam 13 obliquely extends from the bracket 11 toward the upper hinge 6 in upwardly spaced relationship to the lower cross beam 12, and has front and rear ends coupled respectively to the bracket 11 and the vertical beam 10.
  • the upper hinge 7 is fixed to the front vertical surface of the vertical beam 10
  • the front end of the upper cross beam 13 is fixed to the rear vertical surface of the vertical beam 10.
  • the upper cross beam 13 is more slender than the lower cross beam 12, i.e., has a smaller cross-sectional area than the lower cross beam 12.
  • the cross beams 12, 13 are in the form of rods having circular cross section.
  • the upper cross beam 13 has an inner edge substantially aligned with the inner edge of the lower cross beam 12.
  • the vertical beam 10 has a hollow rectangular cross section, whereas the bracket 11 has a deformed channel-shaped cross section.
  • the front ends of the cross beams 12, 13 are coupled perpendicularly to a rear vertical web 9 of the vertical beam 10.
  • the rear ends of the cross beams 12, 13 have respective inner edges coupled parallel to an outer web 14 of the bracket 11.
  • the door opening 15 which can be closed by the motor vehicle door 1 is smaller than the motor vehicle door 1.
  • the window frame 4 has a front lower end joined to the vertical beam 10 as by welding and a rear lower end joined to the bracket 11 as by welding. More specifically, as shown in FIG. 3, the front lower end of the window frame 4 is joined to an upper end portion of the vertical beam 10. Similarly, the rear lower end of the window frame 4 is joined to an upper end portion of the bracket 11. Therefore, the window frame 4 is anchored highly rigidly to the hollow door body 5 of the motor vehicle door 1.
  • the vertical beam 10 comprises a curved beam which projects convexly outwardly and extends along the outer panel 2.
  • the vertical beam 10 has a lower end portion 17 extending downwardly beyond the lower hinge 7.
  • the lower end portion 17 is positioned in laterally overlapping relationship to a lower corner 16 of the door opening 15, i.e., is positioned immediately laterally of the lower corner 16.
  • the motor vehicle door 1 shown in FIGS. 1 through 5 operates as follows:
  • the motor vehicle door 1 has an improved ability to resist external forces applied laterally thereto.
  • the cross beams 12, 13 have different cross-sectional areas for the following reasons: Lateral external forces are typically applied to the motor vehicle door 1 when the motor vehicle door 1 is laterally hit by another motor vehicle such as an automobile. Since such another motor vehicle usually has a bumper in a low position, the lower cross beam 12 is often hit by the bumper of the other motor vehicle. Therefore, the lower cross beam 12 has a larger cross-sectional area or is thicker than the upper cross beam 13 for a greater rigidity against deformation. In FIG. 14, part of the forces applied to the lower cross beam 12 is transmitted through the vertical beam 10 to the lower corner 16 of the door opening 15, which efficiently bears the transmitted forces.
  • the upper cross beam 13 of smaller cross-sectional area has a smaller weight than the lower cross beam 12.
  • the motor vehicle door 1 is also advantageous in the context of its normal usage, as described below.
  • the vertical beam 10 and the cross beams 12, 13 are arranged as a substantially triangular truss with the lock 8 positioned on its vertex.
  • the substantially triangular truss the lower thicker cross beam 12 serves to bear compressive forces and the upper thinner cross beam 13 serves to bear tensile forces.
  • Such a reinforcing truss incorporated in the motor vehicle door 1 is effective to make the motor vehicle door 1 resistant to vertical flexure.
  • motor vehicle front door has been described as the motor vehicle door 1 according to the present invention
  • principles of the present invention are applicable to a motor vehicle rear door, and also to any of various motor vehicle doors other than automobile doors.
  • the motor vehicle door according to the present invention may have three or more cross beams with the lowermost cross beam thicker than the other cross beams.
